GAS ENGINE.

Application filed September 14, 1925.

This invention relates to an attachment for internal combustion engines.

The invention more particularly relates to an attachment for the breather tube or pipe of an internal combustion engine.

The purposes of a breather tube for an internal combustion engine are well known. In the case of an engine employed on a Ford automobile, the breather tube is IO cated at the forward end of the engine and immediately at the rear of the engine cooling fan. The breather tube is closed with a cap of a known construction which is provided with vents. It is also known that heated air and gases collect in the crank case of the engine and the same are laden with oil vapor. The commingled oil vapor laden air and gases enter the breather tube and condense in the tube cap. The condensation escapes through the vents of the breather cap and is blown rearward by the engine cooling fan. This condensation lodges upon exposed parts of engine and lower side of the associated hood, and collects dust and dirt to form a sticky and greasy mass.

With the above in View the purpose of this invention is to provide means whereby the blowing of condensation rearwardly so from the breather pipe or tube of an engine can be avoided.

The object of this invention is accomplished by the provision of a breather tube extension whereby heated air and gases laden with oil vapor may be expelled at a point where the same will not cause a greasy deposit upon the engine and parts beneath its hood.

The invention is illustrated by way of example in the accompanying drawing, in which v Figure 1 is a fragmentary perspectlve view of an internal combustion negine and showing the present invention applied.

Figure 2 is a longitudinal sectional vlew of the attachment, and

Figures 3 and 4- are sectional views taken on the lines 33 and 4-4, of Figure 2.

Referring to the drawings more particularly, 10 indicates generally an internal combustion engine of which 11 is the cooling fan, and 12 the breather tube. There is also shown the usual dust pan as at 13. Also it should be here pointed out that usually the current generator employed in connection with the ignition and lighting system Serial N0. 56,281.

of a motor vehicle of the type referred to is located at the rear of the breather tube and consequently becomes covered with a greasy deposit. This is also true of wires extending to the commutator located at the forward end of engine crank case.

In the present invention the usual breather cap is not used. There is a provided a breather tube attachment generally indicated by the reference character 14, which is in the form of a tube preferably rectangular in cross-section as shown to advantage in Figure 3. The tube is of sufficient length to extend from the breather tube 12 to a point beneath the dust pan 13, an opening being provided in said dust pan through which the tube may be extended as shown in Figure 1.

As seen in Figures 1 and 2, the upper end of the tube is formed-with a laterally bent portion 15 which terminates in a circular headlike formation 16. The head 16 is provided on its lower side with a nipple extension 17 which communicates with the interior of the tubular member 14.- and which is adapted to fit within the breather tube 12 as shown in Figure 1. The upper side of the head 16 is also provided with a nipple extension upon which there is fitted a cap 18 adapted to tightly close the same. The cap 18 may be easily removed when it is desired to pour oil into the crank case of the engine.

As shown in Figure 3, the lower end of the breathertube attachment or extension. is preferably'formed with an inwardly bent portion 19,.the sides of which are slotted as at 20, and said slots diverging upwardly as shown.

It is believed from the description heretofore given of our invention the operation thereof can be clearly understood. It should be pointed out that the attachment is inexpensive to manufacture, and also that the same can be quickly and easily applied.

In the description of our invention, it has been shown that our invention is particularly adapted for an engine of a certain and well known type of motor vehicle. It isto be understood, however, that our invention is not limited to this particular adaptation, as the same may be used on any engine having a breather tube and an extension therefor is desired.

We claim In a motor vehicle construction, an engine llU having a breather tube and a dust pan,

a breather tube extension attachment having a hollow head member provided with an inlet opening and fitted upon the open end of the breather tube, said head also having an oil inlet, a tubular member extending down- 5 wardly from the head and through the dust pan and terminating in a free end below said dust pan, said free end being provided with a nozzle having slots across which the air is adapted to rush when the vehicle is in motion to provide an aspirating effect 10 in the tubular member and the breather tube.
